Expanding Foam Gap Tape

Flexible PUR foam impregnated with a fire resistant polymeric dispersion (DIN4102, Part1, Class B1), suitable for internal and external draught & weather sealing applications.
Supplied in pre-compressed rolls with a self-adhesive backing on one face, the product is inserted into the gap where it expands to form a seal.
Provides good thermal insulation and noise control, seals against uneven surfaces, ideal for timber constructions.

The degree of compression in situ determines the effectiveness of the seal, when used at 80% compression will provide a weatherseal to 600Pa.Lower compression ratios may be suitable for less demanding applications
